[Zope] Pseudo E-Mail Address validation

[Martin Winkler]

Hi all,

For a subscription tool of a mailing list I'd like to quick-check the 
e-mail address our users type. Is there a little product/method etc. 
available that does this? I know that you can only be sure whether an 
e-mail address exists or not, when you actually send a mail to the user, 
but a quick-n-dirty check would be nice. Maybe even complete RFC-compliancy 
as implemented in some Perl-Modules? (spaces, "@" sign, dot-notation etc.)

Hoping for an answer,

Martin
